how to send data between view controllers without using segue in IOS 9

Question

I displayed all phones contacts and I want to send selected contacts to another view controller. I took the selected data into array. There is no segue between two view controllers. I want to send data with out using segue.

Are you moving to that controller after selection? If yes, then which technique are you using to move? — Dipak Kacha, Nov 07 '17 at 12:51

" to another view controller" And how are they linked? What's the order of navigation? Childs? What's your ViewController architecture in your app? How do you present the second one? — Larme, Nov 07 '17 at 12:54

You can instantiate the destination view controller using storyboard instance and pass the data further :

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let controller = storyboard.instantiateViewController(withIdentifier: "TestViewController") as! TestViewController
controller.variableX = self.variableX
self.present(controller, animated: true, completion: nil)

It can be any variable like String, object, collection, whatever you want to set. – Nitish Nov 07 '17 at 13:04
can I set array to it – Lahari Areti Nov 07 '17 at 13:07
Of course. Anything you want to set, you can set. – Nitish Nov 07 '17 at 13:08
In next view controller I have to mention variables? – Lahari Areti Nov 07 '17 at 13:11
@LahariAreti Obviously, just create a property of that type which you are going to pass (in your case create an blank array) in your destination (ViewController the your are presenting or pushing) and then pass you selected value to it. Then, you can easily access your passed details in destination viewController. – bestiosdeveloper Nov 07 '17 at 13:11

@LahariAreti : Can you place a breakpoint in the above code and check if your first viewController array has some value. And then place a breakpoint in viewDidLoad of second viewController and see what is the value of the array. – Nitish Nov 08 '17 at 11:23
